This publication is a useful resource that shell egg producers can use to identify egg defects and possible factors contributing to egg quality issues. It also provides corrective measures for each defect so that producers can incorporate these solutions into their production systems.

Because of increasing economic pressure related to capital costs, egg prices, feed prices, and replacement pullet costs, the commercial egg industry must maximize the use of its resources. The need to lower production costs have led many enterprises to use induced molting programs.
